Worked like a charm. I was interested in controlling my therm over the internet/network. Plugged in the device, added to my them and works perfectly. Company did a great job getting it out and in my hands promptly.

Only gave 4 stars since I have yet to own this for a month. Easy to install and the website is fairly easy to navigate and set up. Each gateway can link up to 4 thermostats (This is NOT in the documentation) Be sure to give a different name to each thermostat. Also, if you need to erase a link-up in the gateway, press and hold the link button for 15 seconds. (Also not documented) You can unlink a thermostat easily in the installer options / wireless setup and this part is documented. This is handy for initial testing prior to installation of a given thermostat.

I do not know the reliable range for the wireless link as my gateway is only a few feet from the theromstat.

Once again, good but too expensive, as a Wifi capable thermostat from others start at [$], but since I have a prestige, I am kinda locked in to get this to make my prestige WiFi capable. Very easy to install, but if you have a prestige, this device won't show up in the list of devices added, it was not mention in the instructions, but it's in the FAQ in Honeywell website.
